Description

Technical Field

[0001] The invention belongs to the field of automatic cleaning devices for glue spray nozzles, and in particular relates to an automatic cleaning device for glue spray nozzles used in a foaming process in the field of automobile manufacturing and a method for using the device. Background Art

[0002] Most existing automotive interior components, including headrests, seat cushions, roofs, and door trim panels, are manufactured using a foaming process. During the automated foaming process, when two different liquid polymer raw materials are mixed according to process requirements and sprayed from a spray nozzle into contact with air, a rapid chemical reaction occurs, forming a colloid that gradually solidifies. This colloid often adheres to the nozzle, blocking it if not cleaned promptly. This can lead to unstable process ratios and compromised product quality. When this occurs, the traditional approach is to shut down the machine to clean the nozzle or replace it with a new one (by removing and cleaning the nozzle). This approach not only impacts production schedules, but also makes it difficult to maintain process standards if the nozzle is not cleaned regularly.

[0003] Chinese patent CN 210434751 U discloses an "automatic cleaning device for a glue nozzle," and CN 110976169 A discloses a "residual glue cleaning mechanism for a glue nozzle." Although these two cleaning devices can automatically clean the glue nozzle, they are ineffective and incomplete, and their structures are too complex to guarantee the sustainability and high-standard stability of the foaming production process. Summary of the Invention

[0021] Advantages and beneficial effects of the present invention:

[0022] (1) The automated cleaning equipment provided by the present invention has a simple structure and can clean the residual glue remaining in the glue nozzle faster and better. It can be directly applied to the foaming process. During the foaming process, after the glue spraying robot completes the previous glue spraying work, it will drive the glue spray nozzle to the soft cloth part of the cleaning equipment to clean the first part of the residual glue. The soft cloth performs preliminary residual glue treatment on the glue spray nozzle and completes the cleaning of 70%-80% of the residual glue. Then the glue spraying robot drives the glue spray nozzle to the second part. The second part cleans the remaining 20%-30% of the residual glue through the rotating cutter head to complete the final cleaning of the residual glue. The entire residual glue cleaning process takes 4 seconds, which is simple and fast, and does not affect the production rhythm and production efficiency while ensuring the cleaning quality.

[0023] (2) The soft cloth of the automated cleaning equipment provided by the present invention is driven by a servo motor and rotates forward according to the process rhythm and the pre-set cloth forward size. The new working surface is replaced from time to time to ensure the cleaning effect. In addition, the soft cloth pre-stored on the storage shaft can meet the needs of continuous production for many days (the soft cloth of the equipment is replaced every 20 days). This greatly reduces the intervention of personnel in the equipment and improves the production capacity of the equipment and the product quality of parts.

[0024] (3) The automated cleaning equipment provided by the present invention utilizes the principle of repulsion between like magnetic poles to achieve the buffering and pre-tightening requirements when the equipment is docked with the glue nozzle. This form greatly reduces the complexity of the equipment, making its structure simpler and also facilitating subsequent repair and maintenance.

[0025] (4) After the rotary cutter head of the automatic cleaning equipment provided by the present invention completes the peeling, the rotary cutter head is automatically cleaned by the internal high-pressure gas to avoid affecting the peeling effect next time, and to ensure that the residual glue can be thoroughly cleaned after each peeling. In addition, timely cleaning of the cutter head can also extend the service life of the nozzle cleaning equipment, reduce the number of equipment shutdowns for maintenance, and improve production efficiency.
